This is an action-packed game making very good use of the C64's sound and colour features. Your spacecraft is loaded within a matrix. Its mission - to clear the zone of droids (snake-like creatures racing around).
While avoiding the bombs from the droids, you also have to avoid the laser beams fired vertically and stay clear of delayed action bombs fired horizontally across the matrix.
If, by some miracle, you clear the zone of droids then you proceed to the next higher zone, of greater complexity. There are 20 zones in all.
On your travels through the zones you are likely to meet nasty humanoids who point out your position to the enemy, deflector beams that rebound your shots, and caravans of camels (Llamas?). When you get hit, you explode in a multicolour shower of sparks with equally impressive sound effects.
The instruction card is very good, setting the scene for the game and giving a detailed explanation of the scoring, etc.
